Breaking capacity reaches 121 kA at 240 V AC, 75.6 kA at 415 V, and 52.5 kA at 440 V — numbers that tell you it can clear high-fault currents in a low-voltage industrial distribution panel without needing a current-limiting fuse upstream.
The 160 A rating holds flat from 40 °C up to 50 °C, then derates gradually to 144 A at 70 °C. That means in a warm cabinet — say 55 °C — you still have 153.6 A continuous capacity, so the breaker doesn't force a de-rate of the downstream load unless ambient exceeds 50 °C. The TM240 release is a thermal-magnetic type with adjustable long-time delay (tr max. 1 s at 6× Ir per), suited for general distribution where you need fixed magnetic pickup and a thermal curve that tracks cable heating. Rated insulation voltage is 800 V, so the breaker is suitable for 690 V line-to-line systems — the 11.9 kA breaking capacity at 690 V confirms it can interrupt faults on a 690 V network, though that capacity is lower than at 400 V class.
Auxiliary contacts and integration
This variant ships with four auxiliary switches (HQ type —), giving you status feedback for remote monitoring or PLC inputs without adding a separate contact block.
